    <h3><strong>How Satellite Communications work:</strong></h3>
    <p>
        Satellite communications work by your computer sending a request through the satellite dish on or near your house which broadcasts to a 
        satellite in a geosynchronous orbit and the satellite then retransmits that signal back down to a central hub.  At the central hub, the 
        request is then sent to the internet.  To get the requested data back to your house, the opposite path is taken, from the Internet, to the 
        hub, back up to the satellite and then back down to your dish before coming back to your computer.<br/>
        Satellite communications typically have high latency.  If you are doing web browsing, you would probably not notice a difference, but if 
        you are doing gaming, using VoIP, or VPNs you will notice the latency.  However, in rural areas, this may be the only choice for Internet connectivity.

    <h3><strong>Providers:</strong></h3>
    <p>
        <a href="http://www.viasat.com/">Viasat.com</a>&nbsp;/&nbsp;<a href="http://www.exede.com/">Excede.com</a>
        <ul>
            <li><strong>ViaSat:</strong>
                The California company bought WildBlue, a satellite broadband provider, in 2009 with plans to broaden coverage. But hampered by 
                the old satellite's limited capacity and slow transmission speed, WildBlue's growth stalled at about 400,000 customers. "It wasn't a 
                service we were proud of," says ViaSat CEO Mark Dankberg.
                With a new satellite launched last year, ViaSat began selling the new service in January under a new brand, "Exede." The download speed 
                will increase to about 12 megabits per second from 1.5 mbps on the old service, Dankberg says. Pricing starts at $50 a month for 7.5 
                gigabytes, not including overage fees.<br/>

            <li><strong>Excede12:</strong>
            All plans have up to 12 Mbps downstream; up to 3 Mbps upstream
                <ul>
                    <li>7.5 GB/month: $49.99</li>
                    <li>15 GB/month: $79.99</li>
                    <li>25 GB/month: $129.99</li>
                </ul>

                    <li>Uses the Gen4 internet service.</li>
                    <li>Manufactures their own satellite internet equipment</li>
                    <li>Gen4 is expected to provide around 20 Mbps downstream</li>
                    <li>‘Exchostar-XVII’ - high capacity satellite</li>
                </ul>
            </li>
        </ul>
        On the chart below, the following providers now use the exede satellite connection:
        <ul>
            <li>WildBlue</li>
            <li>MyBlueDish</li>
            <li>GotSKY</li>
            <li>Dish Network</li>
        </ul>
        <strong>Technologies and companies are changing so rapidly in the satellite markets. *This review for 2012 is already out of date:</strong><br/>

        <h3><strong>Security:</strong></h3>
        Due to the nature of satellite Internet communications, it leaves the signal to be open to be captured by other people.  While encryption helps, many providers are either not encrypting the connections or have very low encryption in order to speed up the connection.  While researching this topic, we found a white paper written on the subject as well as a couple of articles.  See the links below.

        <strong>Provider Security Options</strong>
        <ul>
            <li>HughesNet: Zonealarm Antivirus</li>
            <li>MyblueDish: Fsecure Antivirus</li>
            <li>GotSky: Fsecure Antivirus</li>
            <li>StarBand: Not provided </li>
        </ul>
    </p>
    <p>
        <h3><strong>Scalability:</strong></h3>
        Most companies that we looked at had variable rates based on usage amounts.  The more you use, the more you pay.  If you exceed the monthly allotment of usage, the satellite will slow to a crawl until the next period (varies based on provider).
